Same form factor as a Curve.
GPS.
WiFi/UMA/3G/BT2.0
3MP camera with autofocus.
24 fps video capture.
Hydrogen cell that will run for a month without recharge.
2 GB DDR memory.
Simultaneous voice/data over all protocols.

But if I can't have all that...I'll be happy with a faster processor, a bit more memory (128?), 3mp camera, GPS and WiFi all in one case, Curve form factor please!
